Help with purchase 2008 E550 for iphone
http://wireless4mb.com/

iPhone 3GS works fine in 2006 E500 with the MB Bluetooth interface. Downloads phone book fine, and as an added bonus the iPhone ringtones come through the car speakers.
While the electonics may differ in 2008 (I forget which year the BT was integrated into the COMMAND system), I'd like to think they wouldn't take a step backwards (but hey, it's MB)...
If you want to dock the iPhone in the glove box for audio integration as well, you may need the Scosche Passport adapter to simultaneously charge the phone (it's $17 at Amazon). Apple switched from the firewire to USB pins for charging on the dock connecter several years back and MB took a couple of model years to update the iPod integration cable. So if you get a charging not supported message when you plug the phone into the glove box cable, then you need this little adapter -- without it the iPhone will play through the audio system, but not charge.
Note - it does not connect for music.
